IMPROVEMENT IN WATCH-KEYS.

To ALL WHOM IT MAY CONCERN:

Be-it known that I, WILLIAM LINDON, of New Haven, in the county New Haven, and State of Connecticut, have invented a new Improvement in Watch-Keys; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view of the key,

Figure 2 a side view of the sheath, and

Figure 3 a side view of the key with the sheath placed thereon.

This invention relates to an improvement in watch-keys'or other tubular keys, the object being to prevent the filling up of the tube; and the invention consists in the construction of a sheath to cover the end or tube of the key when not in use, and so as to be easily removed when required for use. i

In order to the clear understanding of my improvement, I- will proceed to describe the same as illustrated in the accompanying drawings.

A is the tube of a watch-key, of common construction. B, a sheath, formed from suitable metal, as thin as may be, its upper end slitt'ed, so as 'to form points, as seen in fig. 2, which are turned inward; the said sheath being formed so as to slip on to the tube, and. the said spring-points spring into an annular groove, 0,

around the key, as seen in fig. 3, and thus cover the end of the tube, and prevent any substance entering the tube; When required for use, the sheath is easily removed from the tube, and after use is as easily replaced.

I do not broadly claim the construction of watch-keys so as to be inserted into and form a part of another instrument, as such, I am aware, is notnew, as seen in the English patent of William Vale, No. 298, February 3, 1865.

Having thus fully described cry-invention, what I claim as new and useful, and desire to secure by'Letters- Patent, is

A key, provided with a sheath, B, the upper end of which is slitted so asto form springs to secure the sheath to the key, substantially as set forth.

WILLIAM LINDON.
